I've been contributing on SO for a decade and comments like this drive me nuts.
It was a free self moderating tool and people couldn't even ask question properly for people to do the work for them for free. The entitlement is astonishing and to have the gal to call SO toxic just shows how undeserving some people are of any assistance.
Yes use the search bar and yes lock the thread if people can't spend 5 minutes to form their question there is no saving of these fools. Period.
In fact my main reason for stopping to contribute was dramatic decrease of question quality not the AI. Just try to follow the new section for a day and tell me it's not a problem, I'll wait.
